Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It should be understood that the technical solution of the embodiments of the present application may be applied to various communication systems, for example: global system for mobile communications (Global System of Mobile communication, GSM), code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA) systems, general packet Radio service (General Packet Radio Service, GPRS), long term evolution (Long Term Evolution, LTE) systems, LTE frequency division duplex (Frequency Division Duplex, FDD) systems, LTE time division duplex (Time Division Duplex, TDD), universal mobile telecommunications system (Universal Mobile Telecommunication System, UMTS), worldwide interoperability for microwave access (Worldwide Interoperability for Microwave Access, wiMAX) communication systems, new Radio (NR) or future 5G systems, and the like.

In particular, the technical solution of the embodiments of the present application may be applied to various communication systems based on non-orthogonal multiple access technologies, such as a sparse code multiple access (Sparse Code Multiple Access, SCMA) system, a low density signature (Low Density Signature, LDS) system, etc., where, of course, SCMA systems and LDS systems may also be referred to by other names in the communication field; further, the technical solution of the embodiments of the present application may be applied to a multi-Carrier transmission system using a non-orthogonal multiple access technology, for example, an orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM), a filter bank multi-Carrier (FBMC), a general frequency division multiplexing (Generalized Frequency Division Multiplexing, GFDM), a Filtered orthogonal frequency division multiplexing (F-OFDM) system, and the like using a non-orthogonal multiple access technology.

The terminal device in the embodiments of the present application may refer to a User Equipment (UE), an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a User terminal, a wireless communication device, a User agent, or a User Equipment. An access terminal may be, but is not limited to, a cellular telephone, a cordless telephone, a session initiation protocol (Session Initiation Protocol, SIP) phone, a wireless local loop (Wireless Local Loop, WLL) station, a personal digital assistant (Personal Digital Assistant, PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, a terminal device in a future 5G network or a terminal device in a future evolved public land mobile network (Public Land Mobile Network, PLMN), etc.

The network device in this embodiment of the present application may be a device for communicating with a terminal device, where the network device may be a base station (Base Transceiver Station, BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA system, an evolved NodeB (eNB or eNodeB) in LTE system, a radio controller in a cloud radio access network (Cloud Radio Access Network, CRAN) scenario, or the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in a future 5G network, or a network device in a future evolved PLMN network, etc., which is not limited in this application.

Fig. 1 is a schematic diagram of an application scenario according to an embodiment of the present application. The communication system in fig. 1 may comprise a terminal device 10 and a network device 20. The network device 20 is used to provide a communication service for the terminal device 10 and access the core network, and the terminal device 10 accesses the network by searching for a synchronization signal, a broadcast signal, etc. transmitted by the network device 20, thereby performing communication with the network. The arrows shown in fig. 1 may represent up/down transmissions over the cellular link between the terminal device 10 and the network device 20.

In the LTE system, when a terminal device initially accesses or needs to measure a neighbor cell, a cell search process is required, and the purpose of the terminal device performing cell search is to acquire a cell physical ID, and obtain timing synchronization and frequency synchronization information of the system at the same time. The physical layer is differentiated between different cells by physical cell identity (Physical Cell Identities, PCI). There are a total of 504 physical cell IDs, which are divided into 168 different groups (denoted N (1) _id, range 0-167), each group in turn comprising 3 different intra-group identities (denoted N (2) _id, range 0-2). Thus, the physical cell ID (denoted as ncell_id) can be calculated by the following formula:

PSS is used to transmit the intra-group ID, N (2) _id value, and SSS is used to transmit the group ID, N (1) _id value. For FDD system, PSS period occurs on the last OFDM symbol of slot 0 and slot 10 and SSS period occurs on the penultimate symbol of slot 0 and slot 10. For TDD systems, the PSS period occurs on the third OFDM symbol of subframes 1, 6 and the SSS period occurs on the last symbol of subframes 0, 5.

In an NR communication system, designs such as a multi-antenna array, beam forming and the like are introduced, for example, an original cell is covered by a plurality of beams, the beam gain can compensate the coverage reduction brought by using a high frequency band to a certain extent, and meanwhile, the mutual interference can be reduced, and the system performance is enhanced.

The synchronization signal Block SS Block is introduced into the NR, and mainly comprises PSS and SSs, and some SS blocks may further include PBCH, and possibly even demodulation reference signals (Demodulation Reference Signal, DMRS) for demodulating the PBCH. In NR, the length of the synchronization signal may also be increased, for example, may become 127; and may also repeat in the frequency domain such that the synchronization bandwidth is increased by integer multiples. The synchronization signal takes SS Block as the minimum unit, and a plurality of SS blocks form an SS Block group, as shown in fig. 2 below, where the synchronization signal period, that is, the transmission period of the SS Block group is 20ms, and the transmission period of the SS Block group may be considered as the period of transmission of the same synchronization signal Block in the same cell, for example, SS Block #1,SS Block#2,SS Block#3,SS Block#4 may be sent by using 4 beams, where each SS Block may have no interval as shown in fig. 2, or may be time domain units separated by a certain unit, as shown in fig. 3. The timing diagram between different SS blocks in the transmission period of one SS Block group may also be the case of signal crossing as shown in fig. 4.

Fig. 5 shows a schematic block diagram of a method 100 of transmitting signals according to an embodiment of the present application. As shown in fig. 5, the method 100 may be performed by a terminal device, in particular by a user device, the method 100 comprising:

110, determining a time sequence of each of the plurality of synchronous signal blocks in a first period;

120, receiving the plurality of synchronization signal blocks according to the timing sequence of each synchronization signal block in the first period.

The timing of the synchronization signal block herein refers to the time domain resource occupied by the synchronization signal block, and may be in units of time domain units. For example, the resources of the first period comprise 7 OFDM symbols in the time domain, and if the network device sends 3 synchronization signal blocks to the terminal device, the network device tells the terminal device in a certain way which of the 3 synchronization signal blocks are on the OFDM symbols of the first period, so that the terminal device can directly receive the 3 synchronization signal blocks on the OFDM symbols told by the network device.

Alternatively, the time length of the first period may be equal to the transmission period of the plurality of synchronization signal blocks.

It should be understood that, in the embodiment of the present application, the period may be similar to the period of the synchronization signal in the prior art, and may be a transmission period of any SS Block in the same cell, or may be a transmission period of the same beam in which SS blocks are transmitted in the same cell. Specifically, the period may be 20ms as shown in fig. 2 or fig. 3. Wherein, the same SS Block means that the types of the included signals are identical, and the contents of the included signals are identical. If two SS blocks include different signal types or include the same signal types but the content of the signals is not identical, or the beams adopted by the two SS blocks are different, then the two SS blocks are different. For example, SS block#1 includes PSS and SSs, the PSS transmission having N (2) _id of 0 and the SSs transmission having N (2) _id of 10, the employed beam being beam 1; while SS Block #2 also includes PSS and SSs, but the N (2) _id of PSS transmission is 0, the N (2) _id of SSs transmission is 10, and the beam used is beam 2 or SS Block #2 includes PSS, SSs and also PBCH, then SS Block #1 and SS Block #2 are different.

It should also be understood that the terminal device may also determine that a certain Block of time domain resources in a period is used to receive multiple SS blocks, and then the terminal device may only detect the multiple SS blocks on that part of the time domain resources. For example, if the network device transmits 5 SS blocks to the terminal device in one period, the terminal device may determine that the SS blocks are received in the 2 nd to 6 th time domain units in one period, but it is possible that the 5 SS blocks are detected only in the 2 nd to 4 th time domain units. That is, the terminal device need not determine which specific resources each SS Block transmits on at all, and only needs to know the approximate location.

Therefore, according to the signal transmission method, the terminal equipment can receive the SS blocks on the fixed time domain resources by determining the time sequence of the SS blocks in one period in advance, so that the calculation complexity of the terminal equipment can be greatly reduced, the detection time is shortened, and the power consumption is saved.

Fig. 6 shows a schematic block diagram of a method 200 of transmitting signals according to an embodiment of the present application. As shown in fig. 6, the method 200 includes:

210, the terminal equipment determines the time domain position of a synchronous signal block group of a cell where the terminal equipment is located in a first transmission period;

220, the terminal device receives the synchronization signal block sent by the network device according to the time domain position of the synchronization signal block group in the first transmission period.

As described above, the terminal device can receive the synchronization signal block sent by the network device at the corresponding position as long as the terminal device determines which time domain position of the synchronization signal block group of the cell is in a transmission period. It should be understood that the synchronization signal block set is configured to the terminal device by the network device, but the number of synchronization signal blocks actually sent to the terminal device by the network device may be equal to or less than the number of synchronization signal block sets. For example, the network device configures 5 synchronization signal blocks for cell 1, and the network device transmits 3 synchronization signal blocks to the terminal devices in cell 1. The terminal device may detect the 3 sync signal blocks at the determined time domain positions of the 5 sync signal blocks.

Therefore, according to the method for transmitting signals, the terminal equipment can receive the SS Block on the fixed time domain resource by determining the time domain position of the synchronous signal group of the cell in one transmission period in advance, so that the calculation complexity of the terminal equipment can be greatly reduced, the detection time is shortened, and the power consumption is saved.

Optionally, in the embodiment of the present application, the determining, by the terminal device, a time domain position of a synchronization signal block group of a cell where the terminal device is located in a first transmission period includes: the terminal equipment determines the time domain position of the synchronous signal block group in the first transmission period according to the physical cell identifier PCI of the cell in which the terminal equipment is positioned.

As mentioned above, the Physical Cell Identity (PCI) of LTE is a radio signal used to distinguish between different cells, ensuring that there is no identical physical cell identity within the coverage of the relevant cell. The cell search flow of LTE determines that a cell ID packet is used, first, the cell group ID is determined by SSS, and then the specific cell ID is determined by PSS. Principle of PCI planning:

1) The collision-free principle results in at most one cell in the overlap area being detected by the UE if two neighboring cells are assigned the same PCI, whereas the initial cell search is only synchronized to one of the cells, which is not necessarily the most appropriate, called collision. Therefore, when PCI planning is performed, it is necessary to ensure that the cell multiplexing distance with PCI is at least more than 4 layers of sites (refer to the empirical value of CDMA PN code planning) and is more than 5 times of the cell coverage radius.

2) The no confusion-free principle is that two neighboring cells of one cell have the same PCI, in which case if the UE requests a handover to the cell with ID a, the eNB does not know which is the target cell. This is called fusion.

Therefore, the network device can pre-define the mapping relation between the PCI and the time domain position of the synchronous signal block group with the terminal device. As can be seen from the above, the number of PCIs may be multiple, and the transmission period of one synchronization signal group may be less than the number of PCIs, in other words, the number of PCIs may correspond to the time domain position of one possible synchronization signal group. Specifically, the network device may correspond to the time domain positions of different synchronization signal block groups for PCIs of neighboring cells. For example, assuming that a transmission period of one synchronization signal block group includes 7 OFDM symbols and one synchronization signal block group occupies 3 consecutive symbols, possible positions of the synchronization signal block group in the transmission period of the one synchronization signal block group include: the network device may divide the PCI into 5 groups, each group corresponding to the location of a group of possible synchronization signal blocks, and inform the terminal device of such configuration information, and when the terminal device knows the PCI of the cell in which it is located, it can determine at which time domain locations to detect the synchronization signal blocks.

It should be understood that the network device may map all or part of the PCIs to the time domain positions of the above five possible synchronization signal block groups by using a calculation rule, and notify the terminal device of the calculation rule, and when the terminal device obtains the PCIs of the cell where the terminal device is located, it may calculate, according to a preset rule, which time domain positions the terminal device needs to detect the synchronization signal blocks at. In particular, the preset rule may be a function, such as a Hash (Hash) function.

Optionally, in the embodiment of the present application, the determining, by the terminal device, a time domain position of the synchronization signal block group in the first transmission period according to a physical cell identifier PCI of a cell in which the terminal device is located includes: the terminal equipment determines a target time domain offset of the synchronous signal block group relative to a first position in the first transmission period according to the PCI; and the terminal equipment determines the time domain position of the synchronous signal block group in the first transmission period according to the target time domain offset.

The time domain offset may be understood as an offset of a synchronization signal block group of a certain cell in the time domain with respect to a start position of a certain transmission period, as shown in fig. 7 and 8. It should be understood that fig. 7 and 8 are only schematic illustrations, and it is not narrowly understood that the time-domain offset is the start position of the synchronization signal block group, but may be the offset of the second synchronization signal block in fig. 7 and 8 in the time domain for a certain transmission period start position.

Since in an NR system the synchronization signal block sent by the network device to the terminal device may be multiple, that is to say may occupy multiple time domain units. If the terminal device does not know which time domain units the network device may send the synchronization signal block on, the terminal device is likely to detect on the resources throughout the transmission period, which adds to the complexity, power consumption, etc. of the terminal. In the embodiment of the application, the network device may pre-configure the timing sequence of the synchronization signal block group of the cell in advance, and as long as the terminal device is told about the time domain offset of the synchronization signal block group, the terminal device may know the time domain resource occupied by the whole synchronization signal block group. The network device adopts a certain rule to design the time domain offset of the synchronous signal blocks of different cells, thereby reducing the interference among the cells.

Optionally, in an embodiment of the present application, the determining, by the terminal device, a target time domain offset of the synchronization signal block group relative to the first position in the first transmission period according to the PCI includes: and the terminal equipment determines the target time domain offset according to the PCI and the mapping relation between the PCI and the time domain offset.

Optionally, in an embodiment of the present application, the method further includes: the terminal equipment receives first information sent by the network equipment; the terminal device determining a target time domain offset of the synchronization signal block group relative to a first position in the first transmission period according to the PCI, including: and the terminal equipment determines the target time domain offset according to the PCI and the first information.

Optionally, in this embodiment of the present application, the first information is the number of the synchronization signal block groups or timing information of the synchronization signal block groups in the first transmission period, and the determining, by the terminal device, the target time domain offset according to the PCI and the first information includes: the terminal equipment determines the target time domain offset according to the PCI and the number of the synchronous signal block groups; or the terminal equipment determines the target time domain offset according to the time sequence information of the PCI and the synchronous signal block group in the first transmission period.

Optionally, in an embodiment of the present application, the determining, by the terminal device, the target time domain offset according to the PCI and the number of the synchronization signal block groups includes: the terminal equipment obtains the target time domain offset by performing a remainder operation on the PCI and the number of the synchronous signal block groups.

Similar to the above determination of the time domain position of the synchronization signal block group according to the PCI, the network device may also configure the mapping relationship between the PCI and the time domain offset in advance. Or the network equipment and the terminal equipment agree on a rule, and the time domain offset corresponding to the PCI can be obtained by calculating the PCI according to the rule. For example, assuming that the time domain offset is the start position of the synchronization signal block group in one transmission period, the network device may be configured in advance to correspond a plurality of PCIs to one start position through a certain design rule. As shown in fig. 7, one transmission period includes 7 symbols, and then the possible time domain positions corresponding to the synchronization signal block group include four positions of symbols 1 to 4, symbols 2 to 5, symbols 3 to 6, and symbols 4 to 7, in other words, the possible time domain offsets are four values of 1, 2, 3, or 4, and then the network device may divide the PCI into 4 groups, one group corresponding to the time domain offset of 1, one group corresponding to the time domain offset of 2, one group corresponding to the time domain offset of 3, and the other group corresponding to the time domain offset of 4. If the terminal device determines the PCI of the cell where the terminal device is located, the terminal device can determine what the time domain offset corresponding to the PCI of the cell where the terminal device is located is through the mapping relationship, and the terminal device knows the time sequence of the synchronization signal block group of the cell where the terminal device is located, that is, the terminal device knows that the synchronization signal block group is sent in 4 continuous time domain units, the terminal device can know the possible positions of the synchronization signal block group, so as to detect the synchronization signal block at the determined positions.

For another example, the network device presets a rule in advance so that only the above 4 offsets can be obtained for each PCI calculation, so that after knowing the PCI of the cell where the terminal device is located, the terminal device can calculate the time domain offset of the synchronization signal block group of the cell where the terminal device is located according to the preset rule, and further can determine the specific time domain position of the synchronization signal block group according to the calculated time domain offset and the timing specified by the protocol. For example, the preset rule may be to combine other information, such as the number of synchronization signal block groups of the cell in which the terminal device is located, or a mapping method of the synchronization signal block groups.

The preset rules described above will be described below as a few possible examples of implementations.

1. And (3) taking a mould: PCI mod G gets the offset position (G is a value specified by the protocol, or an integer determined according to the system configuration (e.g., SS block mapping method in combination, or number of all SS blocks in a group), or a value that is signaled to the UE via system broadcast)

2. And (3) taking a mould: PCI mod G+offset gets offset position

3. And (3) taking a mould: (PCI mod G) J gets the offset position

4. And (3) taking a mould: (PCI mod G+offset) J gives the offset position

5. And (3) taking a mould: (PCI mod G) J+offset to obtain offset position

Some of the parameters G, offset, J mentioned above, may have the following options (each being an independent option): the value specified by the protocol, or an integer determined according to the system configuration (e.g., the SS block mapping method in combination, or the number of all SS blocks in a group), or a value broadcast by the system to notify the UE.

The number of PCI-bonded synchronization signal block sets is described as an example.

As shown in fig. 7, the number of synchronization signal block groups is 4, and PCI mod 4 has 3 values, including 0, 1, 2, and 3, that is, if the PCI of the cell in which the terminal device is located is 162 and 162mod 4 results in 2, the terminal device can know that the time domain offset of the synchronization signal block group of the cell is 2, and the network device can configure PCIs of different groups for neighboring cells because the PCIs are grouped into four groups of 0, 1, 2, and 3, so that interference of synchronization signal blocks of neighboring cells can be reduced.

The timing of the PCI-express synchronization signal block is described as an example.

As shown in fig. 9, if the interval between each synchronization signal block in the synchronization signal block group is 1, two time domain offsets may be configured, and similarly, PCIs may be divided into two groups, one corresponding to the time domain offset is 0, and one corresponding to the time domain offset is 1, and the network device may configure PCIs of different groups for neighboring cells, so that interference of synchronization signal blocks of neighboring cells may be reduced.

It should be understood that the above various calculation rules are all schematic illustrations, and are not limiting to the present application, and that the PCI is combined with which information to determine the time domain offset in the embodiment of the present application, which is also merely an example.

It should also be understood that the network device may preset another rule, so that the terminal device and the network device can directly determine the time domain position of the synchronization signal block group according to the PCI and other information, not just the time domain offset.

Optionally, in an embodiment of the present application, the method further includes: the terminal equipment receives a first synchronous signal block in the synchronous signal block group sent by the network equipment; the terminal equipment determines the PCI of the cell where the terminal equipment is located according to the first synchronous signal block; the terminal device receives a synchronous signal block sent by the network device according to the time domain offset, and the synchronous signal block comprises: and the terminal equipment receives a second synchronous signal block in the synchronous signal block group sent by the network equipment according to the time domain offset.

That is, after detecting one of the synchronization signal blocks, the terminal device determines the PCI of the cell in which the terminal device is located according to the content of the synchronization signal block, and then the terminal device can determine the time domain offset of the synchronization signal block group of the cell in which the terminal device is located according to the PCI, and further the terminal device can determine which positions of the time domain resources occupied by all the synchronization signal blocks are located, so that the terminal device can detect other synchronization signal blocks at the determined time domain positions.

Optionally, before sending the synchronization signal blocks, the network device may send the PCI of the cell where the terminal device is located to the terminal device through a system message or a broadcast message, so that the terminal device may determine, according to the PCI, which positions of the time domain resources occupied by all the synchronization signal blocks are located, and therefore, the terminal device may detect all the synchronization signal blocks at the determined time domain positions.

Optionally, in an embodiment of the present application, the method further includes: the terminal equipment receives second information sent by the network equipment, wherein the second information is used for indicating the target time domain offset of the synchronous signal block group in the first transmission period; the method for determining the time domain position of the synchronous signal block group of the cell of the terminal equipment in the first transmission period by the terminal equipment comprises the following steps: the terminal equipment determines the target time domain offset according to the second information; and the terminal equipment determines the time domain position of the synchronous signal block group in the first transmission period according to the target time domain offset.

The time domain offset may be determined by the network device in the various manners described above, and the network device directly tells the terminal device the determined time domain offset, so that the terminal device can know where the time domain position of the synchronization signal block group configured by the network device is. The network device may tell the terminal device directly the value or may tell a number so that the terminal device can determine the time domain offset associated with itself directly from this number.

Optionally, in this embodiment of the present application, the second information is an identification of the target time domain offset, and the determining, by the terminal device, the target time domain offset according to the second information includes: the terminal equipment determines the target time domain offset from a plurality of preconfigured time domain offsets according to the identification of the target time domain offset.

The network device can tell the terminal device the configured time domain offsets, and the network device tells the terminal device the identification of the time domain offset of the synchronous signal block group of the cell where the terminal device is located, and then the terminal device can select which time domain offset the network device determines from the time domain offsets. For example, the network device configures 0, 1, 2, and 3 time domain offsets, for a terminal device in a cell with a PCI of 162, the network device may use 2 bits to identify the 4 time domain offsets, for example, may use 00 to identify the time domain offset as 0, 01 to identify the time domain offset as 1, 10 to identify the time domain offset as 2, and 11 to identify the time domain offset as 3, and then the network device may send an indication information with a bit value of 10 to the terminal device, so that the terminal device may determine that the network device configures a synchronization signal block group on the symbol 3 to 6 with the offset of 2 from the 4 time domain offsets, and the terminal device may detect a synchronization signal block sent by the network device on the symbol 3 to 6.

Optionally, in the embodiment of the present application, the determining, by the terminal device, a time domain position of a synchronization signal block group of a cell where the terminal device is located in a first transmission period includes: the terminal equipment receives a first synchronous signal block in the synchronous signal block group sent by the network equipment; the terminal equipment determines the time domain position of the synchronous signal block group in the first transmission period according to the time domain position of the first synchronous signal block in the first transmission period and the time sequence information of the synchronous signal block group in the first transmission period; the terminal device receives a synchronization signal block sent by the network device according to the time domain position of the synchronization signal block group in the first transmission period, and the method comprises the following steps: and the terminal equipment receives a second synchronous signal block in the synchronous signal block group sent by the network equipment according to the time domain position of the synchronous signal block group in the first transmission period.

Specifically, if the terminal device detects the position of one of the synchronization signal blocks in a certain transmission period, and meanwhile, the terminal device can learn the identifier of the synchronization signal block, if the network device configures the timing sequence of the synchronization signal block group in the transmission period in advance, for example, if the network device configures the synchronization signal block group to transmit on 4 continuous symbols, when the terminal device detects any one of the synchronization signal blocks, the terminal device can learn the time domain resource where other synchronization signal blocks are located, so that the terminal device can detect other synchronization signal blocks according to the determined time domain resource of other synchronization signal blocks.

Optionally, in an embodiment of the present application, the timing information includes a number of time domain units of an interval between any two adjacent synchronization signal blocks in the synchronization signal block group, and the method further includes: the terminal equipment receives indication information sent by the network equipment, wherein the indication information is used for indicating the number of the time domain units; the terminal device determining the time domain position of the synchronization signal block group in the first transmission period according to the time domain position of the first synchronization signal block in the first transmission period and the time sequence information of the synchronization signal block group in the first transmission period, including: the terminal equipment determines the time domain position of the synchronous signal block group in the first transmission period according to the time domain position of the first synchronous signal block in the first transmission period and the number of the time domain units.

Optionally, the network device may further send, in advance, indication information to the terminal device, where the indication information is used to indicate the number of time domain units spaced between two adjacent synchronization signal blocks in the synchronization signal block group, and if the terminal device detects the timing sequence of one of the synchronization signal blocks, the terminal device may determine, according to the number of time domain units spaced between two adjacent synchronization signal blocks in the synchronization signal block group indicated by the indication information, possible timing sequences of other synchronization signal blocks.

Further, if the number of time domain units separated between any two synchronization signal blocks is the same, the indication information that the network device can only send to the terminal device may only indicate one interval number, and if the network device also tells the terminal device the number of synchronization signal block groups, the terminal device may determine the possible time domain positions of the synchronization signal block groups configured by the network device. Whether the number of time domain units separated between any two synchronous signal blocks is the same or not, the indication information sent by the network equipment to the terminal equipment can indicate a plurality of intervals, so that the network equipment does not need to tell the terminal equipment about the number of synchronous signal block groups, and the terminal equipment can determine the possible time domain positions of the synchronous signal block groups configured by the network equipment.

For example, the network device configures 5 SS blocks to the terminal device in the cell 1, and the network device configures transmission on the 1 st, 3 rd, 5 th, 7 th and 9 th time domain units in one SS burst period, so that the network device can tell the terminal device that every two SS blocks are separated by one time domain unit, when the terminal device detects one SS Block on the 3 rd time domain unit, the terminal device can sequentially detect SS blocks on other singular time domain units in the SS burst period, and the network device can tell the terminal device how many SS blocks are in total while telling the terminal device that two adjacent SS blocks are equally spaced and the number of the spaced time domain units. For example, the number of time domain units of the interval between any two SS blocks may be unequal, so that the network device may tell the terminal device (K-1) the number of intervals, where K is the number of SS blocks, and after the terminal device detects one of the SS blocks, the time domain resource positions of other SS blocks in one SS burst period may be determined according to the number of intervals (K-1). Or the network device can also tell the terminal device the time domain resource position of the first SS Block in an SS burst period, so that the terminal device can directly determine the positions of other SS blocks according to the interval between every two SS blocks in the plurality of SS blocks and the position of the first SS Block.

Optionally, in an embodiment of the present application, the method further includes: the terminal equipment receives indication information sent by the network equipment, wherein the indication information is used for indicating the number of the synchronous signal block groups; the method for determining the time domain position of the synchronous signal block group of the cell of the terminal equipment in the first transmission period by the terminal equipment comprises the following steps: the terminal equipment determines the time domain position of the synchronous signal block group in the first transmission period according to the number of the synchronous signal block group.

Further, the network device configures a plurality of corresponding relations for the terminal device and sends the corresponding relations to the terminal device. The network equipment indicates information to the terminal equipment, wherein the indication information is used for indicating the number of the synchronous signal block groups, the terminal equipment determines a first corresponding relation among a plurality of corresponding relations according to the number indicated by the indication information, and the terminal equipment determines the time sequence of each synchronous signal block in a first period according to the first corresponding relation.

Specifically, the network device may configure in advance the timing relationship between the number of SS blocks that can be sent to the terminal device and the SS blocks within one SS burst period. For example, the network device may configure 3 SS blocks to be transmitted on the first 3 time domain units of one SS burst period, respectively; or the network device may configure that 5 SS blocks are transmitted on time domain units of 1, 3, 5, 7, 9 of one SS burst period, respectively, etc. Or the network device may also configure the timing of 3 SS blocks and the timing of 5 SS blocks at the same time. In summary, in this indication, the timing of SS blocks is typically configured either statically or semi-statically.

Optionally, in an embodiment of the present application, the method further includes: the terminal equipment receives indication information sent by the network equipment, wherein the indication information is used for indicating the time domain position of the synchronous signal block group in the first transmission period; the method for determining the time domain position of the synchronous signal block group of the cell of the terminal equipment in the first transmission period by the terminal equipment comprises the following steps: and the terminal equipment determines the time domain position of the synchronous signal block group in the first transmission period according to the indication information.

Specifically, the network device may dynamically indicate to the terminal device a specific position of each SS Block group in the SS Block in an SS burst period. For example, the network device may directly indicate to the terminal device that 3 SS blocks to be transmitted are respectively configured on the first 3 time domain units of one SS Burst period. The terminal device, after receiving the indication information, may directly detect the three SS blocks on the first 3 time domain units of the SS Burst period.

Optionally, in an embodiment of the present application, the method further includes: the terminal equipment receives indication information sent by the network equipment, wherein the indication information is used for indicating a first corresponding relation in a plurality of corresponding relations, and the corresponding relation is the mapping of a synchronous signal block group in the first transmission period time sequence; the method for determining the time domain position of the synchronous signal block group of the cell of the terminal equipment in the first transmission period by the terminal equipment comprises the following steps: and the terminal equipment determines the time domain position of the synchronous signal block group in the first transmission period according to the first corresponding relation.

Specifically, the network device may fix the time domain position of the SS Block group in advance in one SS burst period, and may configure various corresponding relations in advance. For example, the network device is configured to transmit 5 SS blocks to the terminal device in advance, and fixes the time domain resource for transmitting the 5 SS blocks in one SS burst period. For example, the 5 SS blocks may be fixed on the first 5 time domain units in one SS burst period; the network device may also fix the 5 SS blocks on the 2 nd, 3 rd, 5 th, 7 th, 8 th time domain units in one SS burst period. The network device may store the two configuration relationships and send the two configuration relationships to the terminal device, and when the network device prepares to send 5 SS blocks to the terminal device, may first send an indication message to the terminal device to indicate one of the configuration relationships, so that the terminal device, after receiving the indication message, may know which configuration relationship is, and then use the configuration relationship indicated by the indication message to receive the SS blocks sent by the network device. For example, the configuration relation may be indicated by one bit of indication information, 0 may be used to indicate the first configuration relation, and 1 may be used to indicate the second configuration relation.

It should be understood that the foregoing various indication manners are only illustrative, and the network device may also implement, by using a combination of the foregoing various indication manners, that the terminal device determines time domain positions of multiple SS blocks within one SS burst period.

Alternatively, in the embodiment of the present application, the indication information may be carried in at least one of a broadcast message, a system message, radio resource control (Radio Resource Control, RRC) signaling, MAC CE signaling, and DCI signaling.

Specifically, in the case where the terminal device does not establish a network connection with the network device, the above-described various indication information may be transmitted through a broadcast message or a system message of the cell; after the terminal device establishes the RRC connection with the network device, the network device may send the above various indication information through RRC signaling, MAC CE signaling, or DCI signaling according to specifications or requirements. The time domain position of the SS Block in one SS burst period may be well defined by a protocol, or may be configured by a network device in a static or semi-static manner.

Optionally, in the embodiment of the present application, receiving the indication information sent by the network device includes: and receiving the indication information sent by the network equipment on a main carrier.

The carrier in the LTE system or the NR system may be used as a primary carrier, and the timing of SS Block in its secondary carrier in one period may be notified to the terminal device by the primary carrier, in other words, indication information may be sent to the terminal device through the above various signaling on the primary carrier.

It should be noted that, the plurality of SS blocks sent by the network device to the terminal device may be the total SS Block number or the partial SS Block number in one cell configured by the network device, and in this embodiment of the present application, the terminal device is irrelevant to the SS Block number configured by the cell, and only focuses on the SS Block number sent by the network device. The plurality of SS blocks sent by the network device to the terminal device may further include a part or all of SS blocks of a neighboring cell of the cell in which the terminal device is located.

Optionally, in this embodiment of the present application, different SS blocks may use different beam transmission, the network device may send a system message to the terminal device or SS blocks corresponding to beams around the beam used by the broadcast message, for example, SS block#1 in fig. 2 uses beam 1, SS block#2 uses beam 2, SS block#3 uses beam 3, if the network device uses beam 2 to send the broadcast message or the system message at the time domain position of SS block#2 in fig. 2, then the network device may notify the terminal device of the time domain position of SS block#3, and then the terminal device may directly receive the SS Block at the indicated time domain position.

It should also be understood that the time domain positions of the various SS blocks configured in advance by the network device may be the time domain position of each SS Block of the maximum number of SS blocks within the cell configured by the network device. If the network device sends the number of the partial SS blocks to the terminal device, the terminal device still detects the configured time domain position. For example, the maximum number of SS blocks in the cell is 4, and the network device configures each of the 4 SS blocks to correspond to each of the first 4 time domain units in one SS burst period. If the network device sends 3 SS blocks to the terminal device, the terminal device still detects the first 4 time domain units, and the terminal device may detect 3 SS blocks in the first 3 time domain units and not detect the last time domain unit. Or it may be detected on the last 3 time domain units and not detected on the first time domain unit. The embodiments of the present application are not limited thereto.

It should also be understood that the time domain unit in the embodiments of the present application may be an OFDM symbol, and may also be a slot, a minislot, or the like.
